The following figure shows the variation of adsorption of `N_2` on charcoal with pressure at different constant temperatures.

Arrange the temperatures `T_1`, `T_2` and `T_3` in the increasing order.

Text Solution

Verified by Experts

The process of adsorption (or condensation) is exothermic so the equilibrium may be represented as: Solid (adsorbent) + Gas (adsorbate) Evaporation Condensation Gas adsorbed on solid + Heat By applying Le-Chatelier.s principle, it can be seen that increase of temperature decreases adsorption and vice-versa. The increasing order of temperature is `T_1 lt T_2 lt T_3`
